Route a product through its full lifecycle — discovery, strategy, portfolio choice, roadmap, UX and requirements, experimentation, delivery handoff, adoption, success, and lifecycle review — by composing existing specialist product skills with phase-entry evidence, handoff artifacts, and escalation rules. Use when evaluating a new product idea, managing a product through its lifecycle, or connecting product phases that currently operate in isolation. Do not use for a single product task that…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Product Lifecycle A thin orchestration bundle that routes a product through nine lifecycle phases by composing existing specialist product skills. It provides **cross-skill routing and evidence handoff** — it does NOT duplicate any specialist's step-by-step methodology.

Entry evidence must exist before the phase starts. Output artifacts are handed off to the next phase through the lifecycle evidence ledger. Every phase has explicit escalation behavior and completion criteria. Full phase contracts are in [references/phases.md](references/phases.md). | # | Phase | Primary specialist(s) | Entry evidence | Output artifacts | Escalation behavior | Completion criteria | |---|---|---|---|---|---|---| …

How to install
mdr add magnus919/agent-skills/product-lifecycle@sha256:d4e89c5e7dddfe77The line at the top of this page pins the label git:20260814.a315b77, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
